Abstract

In an induction system for use with an object processing system, a distribution system is disclosed for providing dissimilar objects into one of a plurality of receiving units. The distribution system includes a conveyor section that travels over a vacuum roller, and the plurality of receiving units arranged generally below the vacuum roller such that an object with a mass will fall toward one of the plurality of receiving units based on both the object's mass and a vacuum force applied to the object through the conveyor section.

Claims (39)

1. A distribution system comprising:

an air-permeable conveyor section that is driven around a plurality of rollers, the plurality of rollers including a vacuum roller at a free end of the air-permeable conveyor section; and

a plurality of receiving units arranged below the free end of the air-permeable conveyor section,

the vacuum roller including openings through which a vacuum force is applied to a plurality of dissimilar objects at the free end of the air-permeable conveyor section,

wherein each object among the plurality of dissimilar objects travels a distance around the vacuum roller before falling from the free end of the air-permeable conveyor section into one of the plurality of receiving units based on both a mass of each object and the vacuum force applied by the vacuum roller to each object through the air-permeable conveyor section.

2. The distribution system as claimed in claim 1 , wherein the conveyor section includes a conveyor material with a plurality of openings defined therein.

3. The distribution system as claimed in claim 2 , wherein the conveyor material is a mesh material.

4. The distribution system as claimed in claim 1 , further comprising:

an adjustable vacuum control system that dynamically adjusts a vacuum pressure to accommodate the plurality of dissimilar objects presented to the air-permeable conveyor system.

5. The distribution system as claimed in claim 4 , wherein the distribution system further includes a perception unit that is directed toward the plurality of receiving units to monitor the plurality of dissimilar objects falling from the air-permeable conveyor section into the plurality of receiving units.

6. The distribution system as claimed in claim 4 , wherein the distribution system includes an adjustable rotational speed control system that controls a speed of the air-permeable conveyor section.

7. The distribution system as claimed in claim 1 , wherein the plurality of receiving units include at least one mobile carrier.

8. The distribution system as claimed in claim 1 , wherein the plurality of receiving units include at least one chute.

9. The distribution system as claimed in claim 1 , wherein the plurality of receiving units include at least one conveyor.

10. The distribution system as claimed in claim 1 , wherein the distribution system includes three receiving units.

11. The distribution system as claimed in claim 1 , wherein the vacuum roller is actively powered to rotate.

12. The distribution system as claimed in claim 1 , where in the vacuum roller is a passive roller.

13. A distribution system comprising:

an air-permeable conveyor section that is driven around a plurality of rollers, the plurality of rollers including a vacuum roller at a free end of the air-permeable conveyor section, wherein the vacuum roller is coupled to a vacuum source; and

a plurality of receiving units arranged below the free end of the air-permeable conveyor section,

said vacuum roller including openings through which a vacuum force is applied to a plurality of dissimilar objects at the free end of the air-permeable conveyor section,

wherein at least one object among the plurality of dissimilar objects travels around the vacuum roller and underneath the free end of the air-permeable conveyor section before falling into one of the plurality of receiving units.

14. The distribution system as claimed in claim 13 , wherein the air-permeable conveyor section is formed from a mesh material.

15. The distribution system as claimed in claim 13 , further comprising:

an adjustable vacuum control system that dynamically adjusts a vacuum pressure to accommodate the plurality of dissimilar objects presented to the air-permeable conveyor system.

16. The distribution system as claimed in claim 15 , wherein the distribution system further includes a perception unit that is directed toward the plurality of receiving units to monitor the plurality of dissimilar objects falling from the air-permeable conveyor section into the plurality of receiving units.

17. The distribution system as claimed in claim 15 , wherein the distribution system includes an adjustable rotational speed control system that controls a speed of the air-permeable conveyor section.

18. The distribution system as claimed in claim 13 , wherein the plurality of receiving units include at least one mobile carrier.

19. The distribution system as claimed in claim 13 , wherein the plurality of receiving units include at least one chute.

20. The distribution system as claimed in claim 13 , wherein the plurality of receiving units include at least one conveyor.

21. A method of distributing a plurality of dissimilar objects across a plurality of receiving units, said method comprising:

driving an air-permeable conveyor section around a plurality of rollers, the plurality of rollers including a vacuum roller that is coupled to a vacuum source and positioned at a free end of the air-permeable conveyor section above a plurality of receiving units;

and

applying a vacuum force through openings of the vacuum roller to a plurality of dissimilar objects at the free end of the air-permeable conveyor section,

wherein each object among the plurality of dissimilar objects travels a distance around the vacuum roller before falling from the free end of the air-permeable conveyor section into one of the plurality of receiving units based on both a mass of each object and the vacuum force applied by the vacuum roller to each object through the air-permeable conveyor section.

22. The method as claimed in claim 21 , wherein the method further includes dynamically adjusting any of a vacuum control system that adjusts the vacuum source and a rotation speed control system that adjusts the rotational speed of the vacuum roller.

23. The method as claimed in claim 21 , wherein the method further includes perceiving perception data regarding the object.

24. The method as claimed in claim 21 , wherein the plurality of receiving units include any of a mobile carrier, a chute and a conveyor.

25. The method as claimed in claim 21 , wherein the receiving units each direct any objects received by a respective receiving unit toward one of a plurality of object processing stations.
